Sometimes the fault is just the contacts on the usb terminals are worn to the point they won't connect properly anymore. Insert the ilk fully. then give it a slight nudge one way or another in a direction which makes the terminals of the usb make harder contact.... gently... you may find that it stays lit while a little pressure is applied and once you get that reliable enough then you could carefully load ilk license manager with another ilok plugged in and start transferring licenses... I wouldn't do the whole lot just a couple at a time. ii did this with a ilok that was on it's way out... good luck !
